Abstract
A novel time-frequency exciser is developed for the removal of chirp-like interferences in direct sequence spread spectrum (DSSS) communications. The chirplet decomposition iteratively expands signals in terms of time-frequency localized waveforms. The interference signal components are highly correlated with chirplets, and are represented by a few of the highest energy components of the decomposition. These components are excised from the received signal, and an excised signal goes through a detector for a decision. The proposed time-frequency exciser outperforms the conventional Fourier transform based excisers for chirp-like interference classes. © 1998 IEEE.
